describe here the assembly of new types of donor−acceptor [2]catenanes from dynamic combinatorial libraries (DCL) in water. These new catenanes contain both the donor and acceptor components in at least one of the interlocked rings, thereby possessing unusual and unexpected DAAD or DADD stacking sequences of the π units in their structures. The efficiency of the catenane assembly process can be enhanced
我们在这里描述了从水中的动态组合库(DCL)组装新型供体-受体[2]邻苯二酚的过程。这些新的链烯在至少一个互锁的环中同时含有供体和受体成分,从而在其结构中具有异常和意外的DAAD或DADD堆积序列。可以通过多种方式操纵DCL平衡来提高链烷烃组装过程的效率:添加客体,改变构件的化学计量比或增加库浓度或溶剂的离子强度。发现链烷的形成及其组成取决于供体构件的几何形状,尺寸和柔韧性的细微差异。
